SQUARE MODULE IN SHEET INTRODUCTIVE MACHINES FOR PRINTING LINES OR BOX FORMATORS

DESCRIPTION Object of the invention

The present invention relates to a squaring module in sheet introducing machines for printing lines or box-forming machines, where the squaring module is intended to square a rear part of the sheets, which is opposite to a front part of said sheets , which can be made of cardboard, cellular polypropylene, etc. The squaring module is automated through the use of motors and other elements that adapt to the dimensions of the back of the sheets; both in regard to the dimensions of the width and length of the sheets and in regard to the height of a lower support of the sheets in its rear. It is noted that the various engines of the squaring module act independently of the other mechanisms of the respective sheet introducing machine; all this without reducing power to these mechanisms and allowing to do so! Control of your various positions in an easy way.

Technical problem to solve and background of the invention

At present, the sheets for printing lines or box forming machines comprise a rear part and a front part where each sheet is manipulated by means of a vacuum device to transfer the sheet to the printing line or to the box former, so that said front part of the sheet is squared by means of adjustable plates only according to the width of the sheets, but there is no known background that includes square modules of the back part of the sheets. In this situation, the fact of not including squaring modules on the back of the sheets makes it difficult and slows the transfer of the sheets to the printing line or box former.

Description of the invention

In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes a squaring module in sheet introducing machines for printing lines or box forming machines comprising:

- A transverse plate configured to support a rear part of at least one

sheet.

- A first squaring device comprising two collateral stops configured to move in a transverse direction to adapt to a width delimited by a rear part of opposite edges of the sheet.

- A second squaring device comprising a rear stop configured to fit against a rear edge of the sheet.

- A lower carriage configured to move in a longitudinal direction to adjust the rear stop against the rear edge of the sheet; where the lower carriage is also configured to engage a rear part of the introducer machine; and where the mobility of said lower carriage drags with it to the squaring module assembly.

The squaring module further comprises a third squaring device configured to regulate the height of an upper carriage that includes the rear stop and the transverse plate on which the sheet rests; where the upper car is located above the lower car; and where the upper car is coupled to the lower car. By means of the vertical mobility of the upper carriage, the height of the transverse plate is adjusted and therefore of the support of the rear part of the sheet.

The first squaring device comprises a pair of spindles configured to rotate; where in these spindles they threaten gliding skates in solidarity with the collateral stops; and where the rotation of the spindles transmit their movement to the glues and collateral stops to be able to adjust said collateral stops to the width of the opposite edges of the sheet.

The second squaring device comprises a transverse axis coupled to the lower carriage; where on said transverse axis end pinons are embedded that are configured to be coupled to longitudinal serrated zippers located at the rear of the introducer machine; and where the rotation of said transverse axis mobilizes the squaring module assembly in the longitudinal direction to adjust the rear stop against the rear edge of the sheet.

The third squaring device comprises cogged jaggers in solidarity with said upper carriage; where said serrated zippers are coupled to vertical glues in solidarity with the lower carriage; and where said toothed zippers mesh with toothed pinions embedded in a transverse shaft configured to rotate and

transmit its movement to the upper carriage by means of toothed pinions and toothed zippers.

The squaring module includes a fixed separator located in a central part of the upper carriage; wherein said fixed separator is configured to separate at least two sheets that rest on their backs on the transverse plate; and where said sheets have opposite edges adjacent to respective collateral stops.

The collateral stops and the fixed separator include upward converging upper angular portions that help to fit the sheets when they are received by the squaring module mounted on the introducer machine.

The squaring module of the invention reinforces the squaring or guiding of the sheets during their introduction to the printing lines or box forming machines; where said sheets are transferred by means of a vacuum device and by means of rotating rollers that are located in a front part of the introducing machine. In this way, the problems increased by long sheets or the double feed module are reduced.

The fact of including the squaring module on the back of the sheets reduces problems caused by long sheets and / or the feeding of double sheets in the transfer of said sheets to the printing line or box former.

Next, in order to facilitate a better understanding of this descriptive report and forming an integral part thereof, a series of figures are attached in which the object of the invention has been shown as an illustrative and non-limiting character.
